Police have appealed for witnesses to the incident to come forward and said the woman’s injuries “could have easily been much worse”.

Detective Inspector Paul Lamb of Wirral CID said: “This incident took place in a public place and I would urge anyone who witnessed the attack or knows who was involved to do the right thing and call police immediately.

“The youths involved joined a larger group in the park and I am sure some of these young people would not want to be associated with such a brutal attack. The victim is understandably shocked at what happened.
